Dakota,
Go over to Ebay, that is where I got mine, last year, for about $20. I saw one just yesterday Buy Now for $40. on mine the the holes had to be enlarge a little. Made in Pasistan, but well constructed.
When Snapshot asked for cartridge boxes, that is the one I mentioned, but could not post a picture of it. Never did see in Snapshots original posting where he only wanted pictures of a Blakeslee box. It surprised me that no one posted a picture of one of these as an alternative.
I also thought about a Dyer box but it is outside of my NCOWS Originals persona time point.
